No one will be forced to undergo substance abuse treatment, nor will anyone be subject to drug testing, San Francisco officials insist. Rather, starting in January 2025, San Francisco’s public assistance recipients who screen positive for addiction on a 10-question drug abuse test will be referred to treatment. Those who refuse or fail to show up for treatment will forfeit the $109 a month that the city grants to homeless adults who qualify for city shelters or supportive housing, or the $712 a month it grants to adults with home addresses.
